BABY-CARRIAGE BOOKING- AND ROLLING MECHANSM.

Application filed December 17, 1925,. Serial No. 76,135.

VThis invention relai-testo new `and useful improvements in baby carriage rocking andv rolling mechanism.

The primary object of the invention is to provide a power driven mechanism by means of which thebasketl or bodyof a baby carriage maybe rocked from side to side and the entire carriage-rolled over'its support ing surface Valternately 1in 'a4 forwardr and l0 then kin a backward direction. Y

A further object ofthe invention is to'y provide speed and distance controls for the y rolling portion of the mechanism.

Other objects and advantages of the in-v vention will be, apparent during the course of the'following description I In the accompanying drawings forming a part of this'speciicationand in .which like f vnumerals are employed to designatel llike parts throughout the same, Y

has suitably secured'to its ,underface the transverselyy extending bars `18V which` have the depending ears' lllocated `intermediate their end sand tot .whicli' the', intermediate portions ofthe transverse'A supporting bars 8 are pivotally connectechras at l15. The

`jbars8 and 18 are lprovided with shock fab,-

sorbing bumpersl 16,'as best 'illustrated' in Figs. 8,4,11 and l2'.

Mounted vabove the.

keyed or fastened to 'a transversely extend thef'driven shaft as itis permanently connected. to theY 'motor 'shaft V20' and lrotates "constantlyLwhen'the `motor 19 is operated. The' outer" endof this driven sha-ftv 28 is suitably journaled in a bea-ring. meinb'e-"24 and has permanently fixed vthereto a bevel gear 25which constantly meshes with abevel gear 26 `connected -to the longitudinally ex# n tending `,shaft 27 which is journaled in the bearings 28 supported by the combination platform and vgear casing 18.

The free end of this shaft 27 -hasper- The basket orbody '12 ofthe carriage Y l front axle 9Wandv con? iiected' thereto4 bythe' brackets 1T isacoin-v binati'on platform and gear casing 18 which' lhas 'mountedthereupon the ymotor .19:V :This finotoris preferablyof the spring lactuated type, although anyv other desired forni of niotor may be employed.V The motorshaft 2O has mounted upontits outerend thelpinion f21vwhich meshes wit-h a gear 22 permanently Ymanently fixed vtlieretoaf-pinion 29 which as at 35, in the cutout portions 36 of the front basket or body supporting bar 8. The upper ends of the bell crank levers 34 havev journaled thereon the rollers 37 which are intended to be placed in engagement with the underface of the front bar 13, secured to the front end portion of the carriage body or basket 12,for causing the said basket or their t'wo fop'erative' positions. When the `-pinions 54 are arranged in one operative f position' they willl be connected to -the'trans- Iversezshaft '58r bythe inner keys 53 andi-will be located'forregistcringwith the-inner '-segbody to rock upon its pivots 15.

It will now be seen' that' when the motor 1.9A is operating, the longitudinally extending shaft 27` will rotate for 'causing the lgear i 30 to rotate. This rotary movementlof the gear 30will pivot the bell crank'lever's 34 in opposite directions for causing theirv roller" Y 'carrying ends 37 to alternately' engage the" Vunderface of'the basket or body carrying f bar 13 for rocking said' basket or body.

' The means employed for rolling the entire carriage alternately in Yforvvardand rear- Warddirections jincludesa compound ring gear structure 38.'.Which is housed within ther Vcombination platform and gear j casing 18 and is mounted upon the vertical shaft 39 carried bythe bearings 24. This compound f gear member 38 has formed on its upper)` 'face two concentric ring gears 40 and 41." 'Adjustable upon the driven shaft 23 is a pinion 42 which is operated by the shift lever n 38 to rotate at different speeds.' One of these y positions is in connection with the key 46 Carried by the drivenshaft 23 and in which (Si)k position the pinion 42V will mesh withthe outer ring gear 41 ofthe member 38. The' second operative'position is with the pinion 42 connected to the driven' shaft`23 by they key 47, carried by the latter, in which posivtion the pinionl 42 will mesh with the inner rring gear 40.` 1t will now be seen that a`y Achange speed connection is providedbetween thedriven shaft 23 and the member 38 and that the locating ofthe pinion 42 intermediate the ring gears 40 and 41 will permit form and gear casing` 18 andabove thefront axle 9 isa transversely extending shaft 48 which has its outer ends, see Figs. 1 and 3,y

ed upon its end a piniony 49a which meshes with the gear 50a. Figure 5 merely illustrates af modified form ofconnection'between the shaft'48 and a front wheel 11.

`A53 andthe reciprocating or loosely mount- L# ed pinions 54. These pinions are actuated by v'the shift levers 55''which-"arey carried by T- shaped *supports 56 slidably positionedin the guides 57. By operating the levers 55,

ythe pinionsl54mayfbe moved into either of ffl.

" when the vv'segmental gear l51 engages one pinion: 54 and will'rotate inthe-opposite direction whenthering'gear 51l meshes with the remaining pinionv 54. The second operative position-for-these pinions 54 is when they"arevconnected' toy the' shaft 48"by*the vferent speedand for different length of time.

4It will now be'seen'thatthemotor 19V-may \be"c'onnected to :the compound vmember bythe pinion 42 for' causing the member 38 tating-member may be connectedto the shaft 48 for causing the latter to rotateiiniopposite directions for Vbrief "periods'and the changing of the 'location of the V pinion's 54 will vary the speed and lengthof yrotation It isv to bey understood thatthe forms of this invention herewith shown andde'scribed as to be taken" as preferred examples of the same, and that various changes inthe shape, 'size,"'and arrangement of partsmay be resorted to 'witl'ioutdeparting froml the vspirit ofthe invention or the scope of the subjoined' claims.
